Material for a skeletal mesh that looks like black and white film dust and lines

Sorry for being a newb. I’m trying to create a material to stick onto a skeletal mesh that looks like the old black and white film that has those white string-looking things and lines. The general idea is that a thing has been pulled out from a black and white film and into the real world. Ideally, the lines, etc. would be animated as though the film were still playing.

Any direction would be greatly appreciated!
